Super excited about the update in older injector technology. A clean starting and clean running 12 valve sounds great. Guess I'm gonna have to pull the trigger now.

Can’t wait to see that late 5.9 your talking about. I’m looking for that type of setup, clean quiet 600+. 12v injectors; Maybe compare your new ones to factory marine and your old extrude, would be nice to see on bench and dyno.

Happy Thanksgiving DDP Team. Lenny had some jerky hung up in the ol windpipe. You guys are top of the line. Keep up the great R&D and keeping these old trucks on the road performing like the new trucks.

Great job Lenny

Great job Lenny and entire Dynomite Team !!!!

Golden info ... Good to understand the newer advancements. 👏 Worth the investment!

Great video. The pilot technology you discussed is very interesting

As always, super informative and very interesting!!!

always like learning about the tech behind the stuff!

this was a very informative video. not that i understood all, but keep posting stuff like this ! def. ear & eye worthy! thank you! fyi... your not old. !! you are Wise! thanks!

Awsome information thanks for sharing.

Commenting for support

I'd love to see what y'all could do with a set of 2.8l Duramax injectors. Keep the videos coming. I'll watch a 30+ minute knowledge bomb video!

Have you tried making the pilot hole setup using a dual rate spring on the pintle so the pilots would fire until the flow went up enough to start activating the big holes?

wow the wealth of knowledge lenny has, still advancing technology on 20 plus year old trucks, i love it and good job. DDP has to be the only company doing stuff like this aftermarket wise for injectors, i mean why would anyone buy anything else but ddp. Question, the new power driven diesel 12v power jet injectors as they call it, as i understand there manufactured by ddp, do those have that pilot technology in those? and what spray angle are those at? how many holes? what size holes?

Hi Lenny I like how you mix dance art with your tutorials. At 10:08 and at 10:35 you were doing The Village People YMCA dance. You are good at injectors but you should hone you dancing skills a bit more. I am in the process of swapping in some of your injectors into my 06 Ram truck. I can't wait for the day I can turn the key to see and feel the difference. BTW should I have my injector lines professionally cleaned? Or is brake clean and air pressure ok?

What could be done for a 12V p-pump if maximum mpg is my goal? Have you worked on this and have any mpg numbers?

I am with "thekid760" I would love to see those videos, some data, dyno run sheets etc. anything!! on the 6 to 700hp 2006 5.9 injectors, especially with a cat still installed. I run Calibrated's tunes and they are the best of the four tuners I have tried and now that they are familiar with DDP injectors I am one step closer to making a purchase. Lenny has talked about their six hole injectors for the 2006 and 2007 5.9s in several videos (I own a 2006) and how they run very clean, quiets down the pinging and rattling and have great tip-in/throttle response, smoke and EGT control with plenty of power but,, all I have to go on are the three or four talking videos. Great info. love the pilot hole idea. I hope to see these show up on their web page with some supporting data soon.

Are these modified injectors more accurate than factory bosch and continental?

I’m old and new with injectors with a 1991 Cummins 6BT with factory Holset and aftercooler Not looking for horsepower increase just better than factory and perhaps properly injectors would be the key to a sweet spot. Not interested in more horsepower because of the Allison AT545 can’t take it. Can you build better than original injectors for me ?. It’s a flat nose bus by the way.

So large nozzle injectors will flow just as little as stocks because of inmproper pressure balance between control area and needle area. Translation: large nozzles are lazy and extend duration time and injector duration with the same energize time. The goal is to mimic stock injector timing with larger higher flowing nozzles. Question- how much bigger of a nozzle before body modification is needed? In other words, accepted timing goes out of spec at what percentage of the nozzle being enlarged. I want to do 60% nozzle swaps. Thank you.

So with all this experience, where is the book that dials the costumer in for best results? Rating hp, fuel mileage, and torque rpm range? Don’t skimp on anything; turbo, manifold, injectors, pumps ( lift and pressure), exhaust system. Of course you will need to include different vehicles and engines. But if you had a catalog we could point at and say this is my goal for now! And Dynamite Diesel is my go to.

Kindly need your advice, if nozzle injector 145° 6 hole x 0,145micron turn to 152° 8hole x 0,155micron could it be done? What's the consequences & benefit? Many thx b4

Is the pilot hole stuff applicable to like a 7.3 Powerstroke?

If spray angle compatibility is so critical then why don't they mark the bowl angle on the piston id label on the box I called tech support at Mahle to confirm what Ken ordered me was 1st gen Cummins spec. Or if you were getting ready to ship me a set of correct angle sticks. I had to explain that Bowl and spray angle matching is a critical aspect for diesel. Definitely a man that worked the gas side of the house Never got him convinced I wasn't blowing smoke up his ass. So have no bowl angle, just a hope and prayer that it's right. And then I don't squeeze the head off of piston from hoseing the piston in my fresh motor.

Superb❤️!! You are late to the party = 'Promosm'!
